HAT SHIELD AND vENTlLAToRx SPECIFICATION forming part of Letters Patent No. 402,182, dated April 30', 1889.

Application filed October 2.3, 1888. Serial No. 288,921. (N o model.)

.To all whom it may concern.'

Be it known that I, VILLIAM P. OCONNOR,

. of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Hat Shields and Ventilatore; and I do hereby declare that the following is a full, clear, and exact description. of the invention, which will enable others skilledin theart to which it pertains to make and use the same, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form a part of this specification. The objects of my invention are to introduce fresh air into the crown of a hat when the same is on the head, to protect the head from the suns rays, ttc., and in the attainment of the foregoing ends to avoid mutilating or disfiguring the hat, to regulate as desired the quantity of air admitted into the hat, to prevent drafts upon the head, and to add unappreciably to the weight of the hat.

my improvement-s are applied.

It consists, essentially, of an inverted-concshaped ventilator having laterally-proj ecting upright wings placed in an opening provided therefor in the vcrown of the hat; of means for raising and lowering said ventilator; of a 'shield having on its under side a vertical stem by `which it is adj ustably and removably attached to the hat, andof certain other peculiarities of .construction and arrangement,

out in the claims.

In the accompanying drawings like letters designate the same parts in the several fig- Figure l -is a side elevation of -a hat to wh ich Fig. 2 is 'a perspective view of the same, with the headshield removed and theventilator raised into working position. Fig. 3 is a vertical medial section of the hat and, ventilator as shown in Fig. 2. Fig. 4; isa perspective view of the head-shield inverted. Fig. 5 is aperspective view of the ventilator-frame. Fig. 6 is a view of the under side of the ventilator. Fig. 7 is a perspective view of a modificationV of the ventilator-frame. Y Fig. 8 shows details of the same; and Fig. 9 is a vertical medialsection, on an'enlarged scale, ofthe ventilator, venti later-frame, and of the head-shield support.

It is now` generally believed and conceded that in many cases headache, insomnia, nervousness, baldness, and other disorders result from wearin g close hats, and that these harmful results may be avoided by the introduction of fresh air into the hat around the head. I ain aware that various devices for this pur'- pose have been devised; but, so far as I am informed, they consist simply of perforations through the hat, or are so constructed as to necessitate their readj ustment for any change of direction of the wind or external air-currents, and, in short, so far as I am aware, all the devices for the purpose heretofore in use are inadequate to effectually ventilate the hat.

A represents au ordinary hat, which may be of the customary shape and material. From the center of its crown a circular piece, C, is cut, which is attached to an inverted cone or conoidal piece, E, so as to project a short distance over and completely around the edge of the latter. of wood or some light material, or may be pressed 'out of sheet metal with concaved sides, as shown in Fig. 9. It has a central vertical threaded perforation for the reception of the adjusting-screw G, as shown in Figs. 3 and 9.

To the inclined sides of the cone E are attached the laterally-proj ecting wings e e, preferably four in number, set at right angles to eachother, as seen in Fig. 6. For the purA pose of breaking anddiffusing the ingoing ai r-currents, these win gs e c are slit vertically through their lower edges, and the sections thus formed are bent alternately in opposite directions, as shown in Figs. 6 and 9.

lA spider-frame composed of a ring, Il, and legs g' g, united at their converging ends to an eye, g, is attached in an inverted position to the inside of the hat around the opening in the crown, as shown in Fig.- `The adjusting-screw Gr is held and turns in the eye g of said frame, and the ring vI-I of said frame is secured by suitable means to the inside of the crown of the hat around the circular opening therein, and projects a short distance toward the center of the opening past its edges, so as to forni a seat for the overhanging edge of the circular top C of the ventila- The cone E is preferably formed IOOi tor when the same is closed, and at the same time to hold the top of the ventilator fiush with the crown of the hat and to break the joint between them. The outer edges of the wings c e pass through notches I l in the inner edges of the ring Il, as shown in Fig. G, and the ventilator is thereby prevented from turning with the adj listing-screw Gin raising and lowering it.

Referring to Figs. 5 and d, the ring H, forming a part of the ventilator-frame, is shown as made of metal with points 7iA h cnt and turned in its outer edges for fastening the same to the hat. Some of the points are cut so as to fold inwardly toward the center of the ring, while others are cut so as to fold transversely thereto over the material of the hat pierced by them. The entire frame, in-

cluding `the ring, legs, and eye, maybe cut and pressed in one piece out of sheet metal. I prefer, however, to employ a ring, Il', of felt, leather, or some similar material in which the legs q2 g2 of the spider-frame are secured by slitting their ends, passing them through cuts in the ring, an d turning the poi nts over it in opposite directions, as shown in Figs. 7 and 3. The ring ll is then glued or cemented in place to the inside of the hat.

B represents the head-shield, which may be made out of any suitable light material, and is preferably shaped to conform to the crown of the hat. To the center of the under side thereof is attached a longitudinally-slotted stem, b, the head h ot' which is interposed and held between said shield and a perforated piece, B", of felt or other suitable materia-l, glued or otherwise attached thereto, as shown in Figs. i and 9.

The stem bis inserted and tits snugly in an externally-threaded sleeve, b2, and the adjusting-screw Gis made tubular, and is threaded on the inside to receive and Work with the screw threaded sleeve b2, as shown in Fig. 9. The stem b is held from turning in the sleeve b2 by a pin, b3, secured in said sleeve and passing transversely through the slot in said stem. The stem b may be thrust entirely into the sleeve b2, and the latter screwed down by turning the shield B snugly against the top of the ventilator, as indicated by dotted lines in Fig. 3. In this position the shield is raised and lowered with the ventilator by means of the screw G. It may also be adjusted independently of the ventilator by drawing the stem b out of or thrusting it into the sleeve b2, and by screwing said sleeve in or out when a greater range of adjustment is desired, as illustrated in Fig. 9.

When not wanted, the shield can be readily removed from the hat and laid aside or drawn down snugly to the ventilator and upon the crown of the hat,when the ventilatoris closed. In this case it re-enforces the crown of the hat and serves to protect and keep the head warm. The opening c in the top of the ventilator for the reception of the stem of the shield may be stopped, when the shield is removed, by a plug or button, N, which is inserted when the shield is in use in the lower end of the screw G, as shown in Fig. 9. The

which prevent the concentration of the incoming air at any particular point. The air escapes at the same time from the hat through the openings on the opposite or leeward side of the ventilator from which the current is diverted, and `thorough `circulation is thus effected.

ll claiml. The combination, with a hat having au opening inthe center of the crown, ofa ventilater placed in said opening and composed of an inverted cone with laterally-projectin g upright wings extending above and below said opening when the ventilator is in working position, substantially as and for the purposes set forth.

2. The combination, with a hat having an opening in the crown, of a vertically-adjustable ventilator placed in said opening and composed of an inverted cone with laterallyprojecting upright wings, and means for raising and lowering said ventilator, whereby the size of the aperture around the same is varied or the openin g is entirely closed, substantially as and for the purposes set forth.

3. The combination, with a hat having an opening in the crown, of a ventilator placed in said opening and composed of an inverted cone, and laterally-projecting wings having their lower edges slit and bent in opposite directions, substantially as and for the purposes set forth.
